Effect of cigarette smoke extract, cisplatin, nicotine and/or ionizing radiation on gene expression in the NCI-H460 human lung large cell carcinoma cell line

To understand the effect of nicotine on sensitivity of cancer cells to radiation or anti-cancer drugs, NCI-H460 human lung large cell carcinoma cells were treated with 6 Gy ionizing radiation or 1 uM cisplatin after exposure to 5 uM nicotine or cigarette smoke extract. Whole genome expression in total RNA extracted from the treated cells was quantified using the GeneChip Human Gene 1.0 ST microarray platform from Affymetrix (Santa Clara, CA).
